Etymology. The specific name is a patronym in honor of the Cuban arachnologist Luis F. de Armas.

Diagnosis. Males of S. armasi sp. n. resembles those of S. medialuna by having a small median apophysis ( Figs 5 B–C, 6B–C), but can be distinguished by having a smaller embolar base process ( Fig. 6 A–C); smaller finger-shaped median apophysis ( Fig. 6A, C ) and a strongly curved apical projection of embolar base in ventral view ( Fig. 6B ). Females resemble those of S. bryantae sp. n. by having an atrial hood projected ( Figs 6D , 7A ), but can be distinguished by having it larger and slightly sclerotized, completely covering anterior edges of epigynal posterior plates ( Fig. 6D ).

Description. Male (holotype MNHNSD 09.1627): carapace orange with the two scarcely distinguishable gray paramedian bands ( Fig. 10B ). Chelicerae orange. Labium and endites light orange; sternum yellow with orange edges. Legs orange, darker from tibiae to tarsus. Abdomen dorsally gray with white spots ( Fig. 10B ), ventrally yellow. Total length 10.4, carapace length 5.3, width 4.0. Eye diameters: AME 0.12, ALE 0.16, PME 0.18, PLE 0.18. Chelicerae 1.7 long, with 3 promarginal and 2 retromarginal teeth. Leg femur length: I—4.0; II—3.9; III—3.5; IV—4.5. Leg spination: I—tibia v2-2-2, p0-1-1, r0-1-1, d0; metatarsus v2-2-0, p1-2-0, r0-1-0, d0; II—tibia v2-2-2, p1-1-0, r1-1-0, d0, metatarsus v2-2-0, p1-2-1, r0-1-0, d0; III—tibia v2-2-2, p1-1-0, r1-1-0, d2-1-0, metatarsus v2-2- 1, p1-1-1, r1-1-1, d2-2-2; IV—tibia v2-2-2, p1-1-1, r1-1-0, d1-1-0, metatarsus v2-2-2, p1-1-1, r1-1-1, d2-2-2. Palp: cymbial groove half-moon shaped, distally closed, reaching ventral margin of cymbium; retrolateral tibial apophysis short and truncated distally; median apophysis small with bifurcate tip ( Fig. 6B ); apical projection of embolar base strongly curved and sharp at tip, resembling a bird head ( Fig. 6B ); embolar base covered by sub-quadrangular ventral small tegular process, directed proximally ( Fig. 6 B–C).

Female (paratype MNHNSD 09.1628): carapace orange, darker in the first anterior quarter, especially at the lateral eyes level; with two light gray paramedian bands ( Fig. 10A ). Chelicerae reddish brown. Labium, endites and sternum dark orange. Legs orange with metatarsus and tarsus dark orange. Palp orange, with tarsus dark orange. Abdomen ventrally orange, dorsally gray with white spots ( Fig. 10A ). Total length 12.1, carapace length 5.2, width 3.9. Eye diameters: AME 0.14, ALE 0.18, PME 0.20, PLE 0.20. Chelicerae 2.2 long, with teeth as in male. Leg femur length: I—3.8; II—3.4; III—3.2; IV—4.2. Palp: claw with five teeth ( Fig. 6F ); spination: patella p1; tibia p2–1–0, d1–1–0; tarsus v0–0–2 p2–1–0, r1–1–0, d1–0–0. Leg spination: I—tibia v2–2–2, p0, r0, d0; metatarsus v2–2–0, p0, r0, d0; II—tibia v1–1–2, p0, r0, d0, metatarsus v2–2–0, p0, r0, d0; III—tibia v2–2–2, p1–1–0, r1–1–0, d1–1– 0, metatarsus v2–2–1, p1–1–0, r1–1–0, d2–2–2; IV—tibia v2–2–2, p1–1–0, r1–1–0, d1–1–0, metatarsus v2–2–2, p1–1–1, r1–1–1, d2–2–2. Abdomen: length 6.4. Epigynum: atrial hood large and slightly sclerotizated, completely covering anterior edges of epigynal posterior plates ( Fig. 6D ); primary spermathecae coiled; secondary spermathecae projected internally; fertilization ducts small and C-shaped copulatory ducts ( Fig. 6 D–E).

Remarks. This species is known from the highland savannas and surrounding pine forests at the National Parks José del Carmen Ramírez and Sierra de Neiba.

Distribution. Provinces of Elías Piña and San Juan, Dominican Republic ( Fig. 9 ).
